setup

This method is called once when the filter is loaded. 'arg',
which may be blank, is the argument specified for this plugin
in IJ_Props.txt. 'imp' is the currently active image.
This method should return a flag word that specifies the
filters capabilities.

run

Filters use this method to process the image. If the
SUPPORTS_STACKS flag was set, it is called for each slice in
a stack. ImageJ will lock the image before calling
this method and unlock it when the filter is finished.
